Answer 1

We have both morphological and genetic evidence that chimps/gorillas are more closely related to us than monkeys.

Darwin didn't know about DNA: he based his theories on things like skull shape. If you look at monkey skulls, human skulls, and then gorilla or chimp skulls, then you can see the similarities.
